Microstructure of high-pressure die-casting AM50 magnesium alloy
Journal Title: Archiwum Odlewnictwa - Year 2009, Vol 9, Issue 2
Abstract
Microstructure analyses of high-pressure die-casting AM50 magnesium alloy are presented. Investigated pressure casting was produced on a cold chamber die-casting machine with locking force at 1100 tones in “FINNVEDEN Metal Structures”. Light microscopy and X-ray phase analysis techniques were used to characterize the obtained material. In microstructure, an -Mg solid solution, Al12Mg17 and Al8Mn5 intermetallic compounds were observed. Different structural constitutes, which consist impurities, were not disclosed.

The effect of casting porosities on cavitational erosion of intermetallic alloy FeAl36
The machinery and equipment elements operating in a turbulent fluid flow, are exposed to destruction as a result of the impact of the cavitation, corrosion and abrasion processes, among which are hardest to minimize the...
Criterion for selection the optimal physical and chemical properties of cobalt aluminate powder used in investment casting process
The aim of this work was to determine physical and chemical properties of cobalt aluminate (CoAl2O4) modifiers produced by different companies and the influence of different types of modifiers on the grain size of high t...
Production of Steel Casts in Two-Layer Moulds with Alkaline Binders Part 1. Backing sand with the alkaline inorganic binder RUDAL
Steel casts in Z.N. POMET were produced in moulds made of the moulding sand Floster. This sand did not have good knocking out properties, required a significant binder addition (4.5-5.0 parts by weight), and the casting...
Life cycle assessment as a method of limitation of a negative environment impact of castings
Casting production constitutes environmental problems going far beyond the foundry plant area. Applying a notion of the life cycle the input (suppliers side) and output factors (clients side) can be identified. The found...
Fractographic research of the C45 steel remelted with a plasma of electric arc
This work presents research into properties of the surface layer of the C45 steel following the treatment with highly-focused thermal stream utilizing the GTAW method. The remelting of the surface layer of the sample was...
